Zookeeper uses zookeeper-3.4.7.tar.gz and kafka_2.10-0.9.0.0.tgz. First, install JDK (jdk-7u9-linux-i586.tar.gz) and SSH. The IP addresses are allocated to kafka1 (192.168.56.136), kafka2 (192.168.56.137), and kafka3 (192.168.56.138 ). The following describes how to install SSH and how to build and use zookeeper and Kafka clusters. 1. Install SSH (1) apt-Get Install SSH (2)/etc/init. d/ssh start (3) ssh-keygen-t rsa-P "" (Press enter three times) Note

1. Use command line1) four common command linesPurpose:Because hadoop is designed to process big data, the ideal data should be a multiple of blocksize. Namenode loads all metadata to the memory at startup.When a large number of files smaller than blocksize exist, they not only occupy a large amount of storage space, but also occupy a large amount of namenode memory.Archive can Package Multiple small files into a large file for storage, and the packaged files can still be operated through mapred

If you read Kafka for the first time, read the distributed message system Kafka preliminary Some people have asked the difference between Kafka and general MQ, which is difficult to answer. I think it is better to analyze the implementation principles of Kafka, based on the design provided on the official website, this
